Ok I got it. It's a CNC PLS 420. Thanks for the helpful clarifications. I really do appreciate it.

I'll give it a look tomorrow. Thanks for all the help

I'm sorry, where would I look? The only identifiers I could find on the filters themselves are what I posted in the first pic. Just a bunch of product numbers. Is it maybe listed on the bottom of them? Edit - I think I'm catching on. Maybe on the label outside the filter tank?

Thanks for the reply guys. I can measure them in a few days. I'm just measuring top to bottom? Here are more pics. (they were taken last year)

Hello all. Can someone help me identify which filters these are? I need to order more, but this is my first time. Pentair r173578?

Thanks again Marty. I'll give it a shot. If it goes south, I'll conquer the inevitable.

Marty, Thanks for your kindness in helping. That's a bummer I need to refill. Is there any way I can keep it this way through the summer and do the draining in the fall when the pool is closed?

Ok, I got more cya reagent. First test - past 100 Second test - diluted as instructed and still didn't make it to the 100 mark, but got half way closer. Third test - I filled the 9191 bottle to #7 with pool water. Then filled the remainder of the bottle to the top with tap water. Mixed...

Thank you. No, I actually didn't do the dilute test. I was guessing, and I agree now, it must have been much higher than I stated. I will do that and get a more accurate number. I'll need to wait until Wednesday to test again, as I'm out of the reagent and more is on its way. I have a...

So, I did a drain/refill. Spent 16 hours draining and refilling at same time. 8 hours one day, 8 hours today. I've tested the water twice over these two periods and the CYA is still showing the same. I'm guessing at 150 because the dot disappears about half way to the 100 mark on the test...

FC is at 9.2 today, so it's improving. Thanks for all the info so far. I'll also keep using the TFP app suggestions. Going to work on drain/refill today.
